2017-12-15beam_block: Improve moving of allocationsBjörn Gustavsson
Use annotations added by beam_utils:anno_defs/1 to move more allocations upwards in the instruction stream. That in turn allows us to optimize away more 'move' instructions.
2017-12-15beam_utils: Add usage/3Björn Gustavsson
To avoid having to call both is_killed/3 and is_not_used/3, add usage/3 to answer both questions in one call.
2017-12-15beam_utils: Add anno_defs/1Björn Gustavsson
Add beam_utils:anno_defs/1 which will add an annotation to the beginning of each block indicating which X registers that are defined. Having that information can improve some optimizations.

Thoose clients signs with sha instead of sha2-*. Try first to verify with the correct one, and if that fails, retry with sha1.

2017-12-14mnesia: Read schema user properties directlyDan Gudmundsson
Doing a proper transaction handling of user properties (in current implmenentation) caused schema_transactions to be quadratic which caused huge startup times for nodes with many tables since the merge schema is a schema_transaction. Do a direct read instead, cheap but implies that the plugin changes will not be visible until the changes are commited and cannot be used later in same transaction, which was possible before if undocumented functions where used.

2017-12-14beam_utils: Refactor combine_alloc_lists() to cover more linesBjörn Gustavsson
There are four uncovered lines in combine_heap_needs/2 and combine_alloc_lists/2. There is no way to reach starting from Erlang source code using the standard compiler. However, they can be reached starting from BEAM assembly code, so we don't want to remove them. We could add a test case that covers the lines using assembly code, but an easier solution is to rewrite the code in a more generic way using sofs so that the code can be covered with existing test cases.

2017-12-12jinterface: add package name for Java 9Vlad Dumitrescu
The Java 9 module system requires a module name to be defined. If none is provided, a default one is used derived from the JAR name, but that one is not very unique and can create problems. The recommended module name is the longest common package name for the source code included.
